FocusFlow - Minimalist Pomodoro Timer
A beautiful, minimal Pomodoro timer to boost productivity. Track tasks, customize durations, and stay focused with a seamless Progressive Web App.

The Challenge
In a world filled with digital distractions, maintaining deep focus is increasingly difficult.
- Context: Productivity often suffers from interruptions and lack of structure.
- Problem: Many time management tools are overly complex, cluttered, or require constant connectivity.
- Goal: Create a distraction-free, accessible tool that strictly enforces the Pomodoro technique without friction.
The Solution
FocusFlow is a minimal, elegant Progressive Web Application (PWA) designed to get out of your way.
- Strategy: Prioritize user experience (UX) and accessibility by building a "install-anywhere" PWA with a clean aesthetic.
- Key Capabilities:
- Customizable Timer: Flexible durations for focus, short breaks, and long breaks.
- Task Tracking: Simple task management to keep objectives clear during focus sessions.
- Cross-Platform: Works seamlessly on desktop and mobile as a native-like app.
Technical Architecture
Built for speed and offline capability.
- Tech Stack: Vue 3, TailwindCSS, Vite, PWA.
- Architecture: A pure client-side application leveraging service workers for offline functionality.
- Key Decisions:
- PWA First: Ensured the app is installable and works offline, making it a reliable utility.
- TailwindCSS: Used for rapid, utility-first styling to achieve a modern, lightweight design.
My Role & Contributions
I designed and developed FocusFlow from concept to launch.
- Full-Stack Development: Implemented the complete application using modern Vue 3 composition API.
- UX/UI Design: Crafted the minimalist interface with a focus on usability and visual calm.
- PWA Implementation: Configured manifests and service workers to ensure a native app experience on all devices.
Challenges & Learnings
- Obstacle: Ensuring consistent "background" timer performance across different browsers and mobile OS battery optimizations.
- Solution: Utilized Web Workers to handle timing logic off the main thread, preventing throttling when the tab is inactive.
- Takeaway: Modern web APIs allow for powerful, native-like utility apps without the overhead of native wrappers.
Impact & Results
- Outcome: Successfully launched a polished productivity tool available on any device.
- Metric: Achieved high Lighthouse scores for Performance, Accessibility, and Best Practices.
- Feedback: Users appreciate the "zero-setup" instant usability and clean aesthetic.
